Benzaldehyde, decanal, undecanal and dodecanal were reacted with hydrogen cyanide in a two phase solvent system aqueous buffer and ionic liquids (EMIMBF4)-B-., (PMIMBF4)-B-. and (BMIMBF4)-B-. in the presence of the hydroxynitrile lyases from Prunus amygdalus and Hevea brasiliensis. When compared to the use of organic solvents as the nonaqueous phase, the reaction rate was significantly increased whereas the enantioselectivity remained good. (C) 2004 Elsevier Ltd.
